Why is the church referred to as the house of the Lord?

The term 'house of the Lord' refers to the church as God's dwelling among His people. According to Hebrews 3:1-6, Jesus Christ is the builder of this house, and its foundation is firmly rooted in Him. Just as every house requires a steadfast foundation to withstand storms, the church's strength lies in Christ, who secures salvation for believers. In 1 Timothy 3:15, Paul emphasizes the church's role as the pillar and ground of truth, underscoring that God’s design for His house is inherently linked to His sovereignty and divine purpose through Jesus.
